Jenny has been invited to her handsome classmate Don Prima's latest party, and she has gotten a tune-up and a new paint job just for the occasion. However, Brit and Tiff are ready to do anything to sabotage Jenny's chances to impress at the party.

Jenny is stuck going to a robot convention with Dr. Wakeman. Snubbed by all the other robots and insulted by Dr. Wakeman's rival, Dr. Phineas Mogg, Jenny finds herself going to a robot called Vee for comfort. However, "Vee" is actually Vexus in disguise, seeking to recruit new Cluster members.

Dr. Wakeman is coming to Tremorton High to speak at a special science assembly about Jenny. Fearing humiliation, Jenny tries to prevent her mother from talking at the assembly.

Crackerjack Cluster inventor Krackus has managed to scatter Jenny's parts all over the world, and Brad, Tuck, and Sheldon must put their friend back together before Krackus can call Vexus on his success.

Tuck admires the Silver Shell, so he manages to convince Sheldon into making him Silver Shell's faithful sidekick, the Tin Can. Being a sidekick is not quite what he expects, though.

A group of aliens worship Jenny after she is mistaken for a "comet goddess". It's fun at first but they soon drive Jenny crazy. However, when confronted, the aliens promise to leave her alone after one last ceremony. Jenny unwittingly pulls the Sun towards the Earth, and uses the same ceremony the opposite direction. She then hurls the alien's spaceship into an elliptical orbit around the sun, turning them into a comet. The Earth is saved, but someone's missing...

With Misty hanging in Tremorton and doing her part in keeping the town safe (though not for free), Jenny decides to leave the superheroics to her and starts to slack off. But when Misty's mercenary habits clash with Jenny's views on protecting the innocent, fisticuffs break out between the two. What's going to become of their friendship?

The Space Bikers have managed to rebuild Jenny into a motorcycle, and now she and Tuck are en route to their hideout to demand them to change her back!

After destroying a series of asteroids that threaten to destroy the Earth, Jenny returns to earth, bringing with her a dust that severely alters the characteristics of her close friends.

Jenny winds up getting homeschooled by Dr. Wakeman due to a mishap at school involving a student and a trashcan. Jenny may not like it, but her mother enjoys the chance to teach her daughter... perhaps too much.

At the Invention Convention, Professor Wakeman's latest robot goes haywire. Soon after, all the previous XJ robot models begin to attack as well. It's up to Jenny and her mother to find out why.
